RING-BAND FOR WATCH-MOVEMENTS.

Specification of Letters Patent.

Patented June 80, 1908.

Application filed October 23, 1906. Serial No. 340,134.

To all whom it may concern:

Be it known that I, CHARLES FUNK, citizen of the Republic of Switzerland, residing at Geneva, in the canton of Geneva, Switzerland, have invented certain new and useful Improvements in Ring-Bands for Watch- Movements, of which the following is a speciflcation.

The present invention relates to an improved ring-band adapted to connect a Swiss watch-work with an American watchcase, the ring band comprising a cylindrical body portion provided with an interior circular bearing or flange intended to support the usual rim of the plate of a Swiss watch movement, and an exterior circular bearing or flange intended to be supported upon the inner rim of the center of an American watch-case, the transverse section of the improved ring-band being approximately a Z.

The drawing shows the improved ring band connecting a Swiss watch movement having its dial set in a bezel, with the case center of an American case.

In the construction shown in the drawing, the plate a is provided with a dial 1) set in a bezel of a ring 0 locked on the plate a and the plate a is provided with a circular rim a.

My improved ring band comprises a cylindrical body portion (1, corresponding in its inner diameter with the outer diameter of the said circular rim a. At one end the body portion d is provided with an internal flange (1 adapted to engage the said circular rim a and thereby support'the plate a, and at the other end the body portion (1 is provided with an external flange d in a diiferent plane to the internal flange d and adapted to engage and to be supported upon an internal circu lar rim 6 onthe watch case center 6 of an American watch case.

The improved ring-band may be made with a depending circular projection adapted to surround the bridges of the watch works, as shown in dotted lines in the drawing, in order to prevent the dust entering the move* ment.

I claim as my invention:

The combination with a watch case center having a circular rim and a watch movement plate having a circular external rim, of a ring band comprising a cylindrical body portion d, an internal flange d at one ed e thereof and an external flange d at t e front edge thereof, the ring band receiving the movement plate with the rim of the movement plate resting against the flange d and the flange (1 resting upon the rim of the watch case center, and a ring 0 having a dial bezel surrounding the movement plate and received therewith within the band.

In testimony whereof I have aflixed my signature in presence of two witnesses CHARLES FUNK. Witnesses L. H. MUNIER. R. DE WURRTEMBERGER.
